NONREFILLABLE-BOTTLCE CAP.

Application filed February 21, 1921.

To all whom it may concern:

Be it lrnown that 1, PAUL FUZY, a citizen of the United States, residing at Sheridan, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in llonrefillablediottle Caps, of which the following is a specification.

This invention relates to appliances for bottles and similar containers, and more particularly to a device adapted to be applied to a bottle of standard type and to effectively prevent refilling of the bottle.

One of the main objects oi": the invention is to provide a device of the character stated of simple construction and operation which may be readily applied to a bottle of standard construction. A further object is to provide a device which when applied. will eliectively prevent refilling of the bottle while permitting, ready discharge of the contents thereof. Further objectswill appear from the detailed description.

In the drawings:

Figure l is a fragmentary side view of abottle of standard type with the device applied.

, Figure 2 is a similar view with the device being shown in central vertical section.

Figure 3 is a top plan View of the device with the cover member removed.

The device comprises a cylindrical body 1 to the inner face of which are secured upwardly and inwardly inclined leaf springs 22 adapted for engagement beneath bead a provided. at the upper end of neck Z) of a bottle A of known type. When the body 1 is placed over the neck of the bottle springs 52 engage beneath head a so as to effectively prevent removal of the device, as in Figure 2.

Adjacent to its upper end body 1 is provided with a central concentric tube 3 connected to the body by a web 4;, this tube being provided with a sleeve 5 of rubber or other suitable material, the tube and the sleeve 5 carried thereby being forced into the upper end of bottle neck I) when the device is applied so as to effect a tight closure about tube 3. The upper end of tube 3 is Serial No. 446,680.

normally closed by a flap valve 6 hinged at 7 to web 4. This flap valve is normally held. seated by a disc 8 secured on the lower end of a rod 9 slidable through a cover 10 which is permanently secured upon the upper end of body 1 by riveting, welding, or in any other suitable manner. A discharge spout 11 communicates with body 1 above web t to per init discharge of the contents of the bottle flowing into the upper portion of the body. Disc 8 is normally held depressed by a coil expansion spring 12 mounted about rod 9 and confined between cover 10 and the disc. To facilitate raising of the disc a ring 13 is secured through the upper end of rod 9.

hen the device is applied disc 8 is pressed upon valve 6 by spring 12 so as to hold this valve closed or seated to prevent escape of the contents of the bottle. By raisirm rod 9 the valve may be unseated suitficiently to permit escape through tube 3 and spout 11 of the contents of the bottle, by tipping the bottle in the known manner. lI'l it is attempted to refill the bottle by forcing liquid through spout 11 the valve will be moved to seated or closed position by the pressure of the liquid thus rendering it impossible to force the liquid through tube 3.

What I claim is In a device of the character described. a boc y provided. adjacent to its upper end with a web element dividing: the body into an upper and a lower compartment, upwardly and inwardly inclined resilient members mounted within the lower compartment of the body, a tubular member depending from said web element and adapted to fit into the neck of the bottle, a valve mounted in the upper compartment of the body and adapted to close the upper end of sail tubular memher, a cover member secured on the upper end of the body, a rod slidable through said cover member, a disc secured on. the lower end of the rod and positioned to press upon said valve so as to hold the same seated, and an expansion coil spring confined between said disc and the cover member.

In testimony whereof I afliX my signature.

PAUL FUZY.
